Hello all,
I am a grad student taking a course in MRC and have a problem with a project
I am working on. I think I may have bitten off more than I can handle with
this one and would appreciate any insight you can give me.
I have data from a longitudinal study in which a type of treatment was
developed for chronic pain. In the analyses, I am looking at the baseline
measures and the final time measures. The main variable of interest is the
pain report at baseline and final.
I am interested in determining if the change in any of the other variables
contributed to the variance of the final pain measure. Specifically,
ratings of depression, anxiety; as well as physiological variables such as
heart rate, blood pressure, and respiration rate.
My problem is that I am looking at change in one variable and trying to
determine how it affects change in another variable. I would like to do an
MR analyses, maybe using the residuals from baseline/time 2.
Any advice?
Thanks in advance!
John.
